求助：在镜像文件上安装grub出错

hbrqlpf

grub> device (fd0) /dev/loop1

grub> root (fd0)
Filesystem type is ext2fs, using whole disk

grub> setup (fd0)
Checking if "/boot/grub/stage1" exists... yes
Checking if "/boot/grub/stage2" exists... yes
Checking if "/boot/grub/e2fs_stage1_5" exists... no
Running "install /boot/grub/stage1 (fd0) /boot/grub/stage2 p /boot/grub/grub.c
onf "... failed

Error 29: Disk write error
问题补充：我是利用/dev/loop1在磁盘镜像文件上安装grub,出现这样的问题

是不是空间不够了,/dev/loop1连到哪个文件?

hbrqlpf

touch hd.img
dd if=/dev/zero of=hd.img bs=1M count=64
losetup /dev/loop1 hd.img
mkfs.ext2 /dev/loop1
mount /dev/loop1 /mnt
cd /mnt
mkdir boot/grub -p
cp /boot/grub/stage1 boot/grub/
cp /boot/grub/stage2 boot/grub/
cd /
然后执行：
grub --device-map=/dev/null
进入grub命令行界面
grub> device (fd0) /dev/loop1

grub> root (fd0)
Filesystem type is ext2fs, using whole disk

grub> setup (fd0)
Checking if "/boot/grub/stage1" exists... yes
Checking if "/boot/grub/stage2" exists... yes
Checking if "/boot/grub/e2fs_stage1_5" exists... no
Running "install /boot/grub/stage1 (fd0) /boot/grub/stage2 p /boot/grub/grub.c
onf "... failed

Error 29: Disk write error

折磨了我一整天了，还是没搞好...

换了台机子执行，还是有错，但错误号又变了
grub> device (fd0) /dev/loop1
device (fd0) /dev/loop1
grub> root (fd0)
root (fd0)
Unknown partition table signature
Filesystem type is ext2fs, using whole disk
grub> setup (fd0)

明白了，好像grub0.97只支持1.44M的软盘镜像文件
